Hi everyone,
I have an old Sea Hornet (Australian brand) rubber powered gun. It is only 70cm. The guns came standard with a screw in bridle and a thin (12mm?) rubber. The gun was given to me and it is in very good condition. The metal components seem to be of a surprisingly high quality and all are spotless. These guns came standard with a rather heavy 8mm stainless shaft. This is the biggest issue with the gun from what I can see as the standard rubber is not powerful enough to propel the spear with enough power.
I had some old bulk rubber (19mm) and decided to make up some rubbers for it with the rigid U shaped bridle with brass balls on the ends which is similar to the standard bridle design. The rubbers I made were 26.5cm lond not including the bridle. I have tried 3 times now but each time I try to load the gun, the rubber breaks half way along where it goes through the hole under the muzzle. Not sure if it my rubber or if this is a common problem with trying to make short rubbers out of thicker rubber tubing. The tension required to load the gun tells me that it will be quite powerful - not sure about accuracy though....
I have lengthened the shooting line accordingly.
The spear shaft does have 2 notches and the hole under the muzzle is elongated so that 2 rubbers could be used. Perhaps 2 x 16mm would be better....
Any advice on getting more power out of such a short gun in order to drive the heavy shaft at a decent speed??
Cheers,
Mark
